my homie knocked me the fuck out when we put on the gloves on one time. He had about 60 lbs on me though, and I was drunk as fuck. Other than that, been in brawls where I hit the ground and they tried stompin on me, but got back up immediately and started swangin them thangs.
boxed for about a year as well, and never got knocked out. took a few bloody noses, but definitly gave a few out as well.
Id rather get knocked the fuck out than let anyone ever disrespect me. Fuck that. Dont care what the size advantage is. And there is always someone tougher than you, so I dont look at someone getting knocked out once as a weakness..if it happens over and over again, than you probably are weak as fuck and need to dodge funk.
